Cov qauv pib ntawm lub tshuab
1. Cov qauv ntawm ib theem 3-theem asynchronous lub cev muaj ib tus stator, lub rotor thiab lwm yam khoom siv.
(1) Stator (tseem tshooj)
1. Stator tseem ceeb ua haujlwm
Siv: Ib feem ntawm cov hluav taws xob sib txuas ntawm lub cav thiab muab qhov stator windings rau nws.
Tus Qauv: Tus qauv stator feem ntau yog tsim los ntawm laminating thiab laminating ib daim ntawv hlau silicon muaj ib txheej insulating rau ntawm 0.35 to 0.5 hli tuab, thiab ib qho zis uas tsis tau sib npaug yog tsim hauv lub voj voos ntawm qhov tseem ceeb rau kev nkag mus rau stator winding.
Nws muaj ob peb hom stator tub ntxhais qhib:
Txuas Txiav Txim Siab: Qhov ua tau zoo thiab qhov muaj zog ntawm lub tshuab muaj ntau dua, tab sis cov cua thiab qhov rwb thaiv tsev yog qhov nyuaj dua. Feem ntau siv cov hluav taws xob tsawg tsawg zog.
Siv Semi-qhib ziab: Nws tuaj yeem siv nrog cov cua moulded, thiab feem ntau yog siv rau cov loj thiab nruab nrab qhov qis qis hluav taws xob. Qhov sib tw hu ua winding, uas yog, lub cua, yuav muab tso rau hauv qhov zawj ua ntej raug insulated.
Qhib hom slot: siv los embed lub tsim winding, txoj kev tiv thaiv kev yoojyim yooj yim, feem ntau yog siv high voltage motors.
2, stator winding
Muaj nuj nqi: Nws yog ib feem ntawm lub cav, uas txuas nrog rau peb theem tam sim no los ua kom muaj kev sib hloov magnetic.
Tus Qauv: Nws yog ua los ntawm peb qhov sib npaug zoo tib yam uas qhov chaw sib cais los ntawm 120 ° lub kaum pob hluav taws xob thiab ua zoo ib yam. Cov coils ntawm cov kev sib tw no muaj feem xyuam rau cov kab nrib nrab ntawm cov stator raws li qee txoj cai.
Lub rwb thaiv tsev tseem ceeb ntawm stator windings yog raws li nram no: (txhawm rau txhim kho kev ywj pheej ntawm qhov chaw nruab nrab ntawm qhov kev sib tw thiab cov tub ntxhais thiab kev ruaj khov ntawm kev nkeeg ntawm lawv tus kheej).
1. Rho phom rau av: rwb thaiv tsev ntawm stator winding thiab stator tub ntxhais.
2. Cov txheej txheem theem-rau-theem: kev ywj pheej ntawm stator windings ntawm txhua theem.
3. Kev Rho Tawm: Cov rwb thaiv tsev ntawm cov kev lem ntawm txhua theem ntawm stator windings.
Thaiv nyob rau hauv lub cev muaj zog hlawv:
Muaj lub davhlau ya nyob twg hauv lub thawv tsav tsheb. Cov xov tooj cua ntawm peb-theem ntawm peb lub vas sab yog ob txoj kab, thiab peb lub tshav dav hlau thaiv sab nraud nyob rau sab sauv yog 1 txog 1 (U1), 2 (V1), thiab 3 sab laug mus rau sab xis. (W1), qhov sib tw hauv qab peb yog 6 (W2), 4 (U2), thiab 5 (V2) ntawm sab laug mus rau sab xis. Txuas mus rau peb lub caij windings rau ib lub hnub qub kev txuas lossis kev sib txuas kev sib txuas. Tag nrho kev tsim thiab txij nkawm yuav tsum tau teem caij raws li kab lus no.
3, puag
Kev Ua Haujlwm: Kho cov stator tub ntxhais thiab lub hauv ntej thiab nram qab kawg lub khwb los txhawb lub rotor, thiab ua si lub luag haujlwm ntawm kev tiv thaiv thiab kev tshav kub.
Siv: Lub hauv paus yog feem ntau cam khwb cia hlau, qhov loj asynchronous lub hauv paus puag yog feem ntau welded nrog phaj steel, thiab lub hauv paus ntawm lub micro engine yog ua los ntawm cam khwb cia txhuas. Muaj cua sov pob tw qaub rau sab nraud ntawm lub kaw tsheb kom ua rau lub zog cua sov tuaj. Qhov kawg lub kaus mom ntawm tus tiv thaiv lub cev muaj qhov cua qhov ntawm ob hnub, kom cov huab cua sab hauv thiab sab nraud lub tsheb tuaj yeem ncaj qha mus rau los pab kom cov cua sov tawg.
(2) Rotor (rotating qhov)
1. Rotor core ntawm peb theem phase asynchronous:
Muaj nuj nqi: Ua ib feem ntawm qhov sib txuas ntawm lub cav thiab qhov rotor windings nyob rau hauv lub hauv paus tub ntxhais.
Kev Tsim Ua: Cov khoom siv yog tib yam li ntawm tus stator. Nws yog ua los ntawm 0.5 mm tuab silicon hlau daim ntawv thiab laminated. Qhov txheej sab nrauv ntawm silicon steel sheet yog punched nrog qhov chaw sib npaug ntawm qhov rotor windings. Lub hauv paus tub ntxhais ntawm silicon steel sheet uas yog tom qab tus tub ntxhais stator feem ntau yog siv los ntaus cov tub ntxhais cov rotor. Feem ntau, lub rotor tub ntxhais ntawm lub cav me me asynchronous yog ncaj qha nias rau ntawm ib qho tig ncej, thiab rotor tub ntxhais ntawm lub cav loj thiab loj nruab nrab asynchronous (nrog lub rotor diameter ntawm 300 mus 400 hli los yog ntau tshaj) yog nias tawm tsam rotating ncej los ntawm txoj hauv kev rotor bracket.
2. Rotor winding ntawm peb theem phase asynchronous lub cev
Kev Ua Haujlwm: Txiav ua haujlwm magnetic los ntawm tus stator los ua kom muaj kev sib tw electromotive quab yuam thiab tam sim no, thiab sib sau cov electromagnetic torque tig lub cav.
Kev tsim kho: faib rau hauv tob tawb rotor thiab mob rotor.
1. Cage rotor: Lub rotor winding muaj ntau tshaj li ntawm cov tuav hauv cov rotor slot thiab ob lub voj kawg ntawm lub nplhaib. Yog hais tias tshem tawm cov rotor core, tag nrho winding zoo li ib tug tawb nas, ces nws yog hu ua ib lub vias winding. Lub me me lub cav xaij cam khwb aluminium rotor winding, thiab yog welded los ntawm tooj liab lub voos thiab tooj liab kawg nplhaib rau cov motors saum 100KW.
2. Mob rotor: Lub qhov txhab rotor winding zoo ib yam li tus stator winding. Nws kuj yog ib qho kab cim peb theem ua qauv. Nws yog feem ntau txuas nrog lub hnub qub. Peb lub hau hau yog txuas nrog peb lub sij hawm tam sim no khaws cov rings ntawm txoj hlaws, thiab tom qab ntawd dhau los ntawm txhuam thiab lwm qhov kev sib txuas ntawm Circuit Court.
Nta: Cov qauv no nyuab dua, yog li daim ntawv thov ntawm lub qhov lub cev tsis muaj zog tsis txuas ntxiv raws li tus cage cage motor. Txawm li cas los xij, los ntawm lub nplhaib thiab tus txhuam, ntxiv cov khoom xws li cov resistors raug tso rau hauv qhov rotor winding Circuit Court los txhim kho kev pib thiab kev tswj kev ua haujlwm thiab kev tswj kev ua haujlwm ntawm lub cav asynchronous. Vim li no, cov khoom siv ua haujlwm khiav ceev hauv ib qho ntau yam, xws li Cranes, elevators, cua compressors, thiab lwm yam. Siv saum toj no.
(3) Lwm yam khoom siv rau peb theem asynchronous motors
1. Xaus hau: kev ua haujlwm txhawb.
2. Cov Kabmob: Nrhav kev paab hab qhov txav txav.
3. Cov kab mob khwv npog kawg: tiv thaiv kabmob.
4. Ntxuam: Txias lub cav.
Qhov thib ob, DC motor txais ib qho octagonal tag nrho laminated qauv thiab ib tug series-zoo siab winding, uas yog haum rau automatic tswj technology uas yuav tsum tau rau pem hauv ntej thiab rov qab rotation. Nws kuj tseem yuav ua nrog series excitation winding raws li tus neeg siv cov kev xav tau. Lub cev muaj qhov nruab nrab ntawm 100 mus rau 280 hli tsis muaj qhov raug mob, tab sis lub cav nrog qhov chaw nruab nrab ntawm 250 mm thiab 280 hli tuaj yeem nrog cov nyiaj them poob haujlwm raws li tej yam kev mob thiab kev xav tau. Lub cev muaj qhov nruab nrab ntawm 315 mus rau 450 hli tau ua kom poob nyiaj. Tus qauv thiab kev cai ntawm lub tshuab nrog qhov nruab nrab ntawm 500-710mm yog nyob rau hauv cov qauv IEC cov qauv qhia ntawv thoob ntiaj teb, thiab cov neeg ua haujlwm me me ntawm kev tsav tsheb ua raws li ISO international standards.
